4 Claims.

This invention relates to improvements in window assemblies generally, but more particularly to double hung window assemblies of both the vertical and side sliding types.

A principal object of this invention is to provide a window assembly with frame means to accommodate interchangeable storm sash and screen panels which are easily applied and removed from within the building.

An object of this invention is to provide an improved window construction for all-metal windows or for metal sash windows having insulation or thermally inert means for retarding the heat transmission through the sash, thus insulating the sash and overcoming objectionable moisture condensation and formation of ice on the sash.

It is also an object hereof to provide a double hung window assembly of both vertical and side sliding types having means between the sliding sash for receiving the interchangeable storm sash and screen panels, such means being an insulator to retard heat transmission through the storm sash and to reduce the likelihood of condensation or ice formation.

The invention consists in a window assembly including a frame with sash slicleways separated by jamb parting strips and head and sill rails made of insulating material, and further including a cross rail located between the meeting rails of the sliding sash when in normal closed posi tion. The invention aiso consists in the pro vision of sash parting strips and rails adapted to receive interchangeable snrm sash and screen panels in the space between the sliding sash. Moreover, this invention consists in the parts of the window assembly and in the combination of parts thereof, as be described and claimed hereinafter.

It has been a problem in connection with the use of all-metal or Wood window frames and metal sash to avoid the objectionable formation of condensation or ice in and around the margins of the window assembly. At the present time, nothing has been made available which will eliminate or reduce this objectionable feature. The present invention is addressed to the problem of reducing, if not eliminating, the objectionable feature of condensation or ice formation on or around the sliding metal sash. This object of the invention is attained by insulating the metal sash through the application of parting strips and rails formed of insulating material. Any suitable insulating material may be employed for these parts of the window structure,

such as wood, plastic or similar thermally inert materials.

The invention is exemplified by a presently preferred window assembly and by certain modifi cations adapted to the use of various materials shown in the accompanying drawings, wherein:

Fig. 1 is an elevational view of a window assembly seen from the interior side thereof;

Fig. 2 is an enlarged sectional elevation with portions broken out, the view being taken at line 2-2 in Fig. 1;

Fig. 3 is an enlarged, fragmentary transverse section taken at line 3-3 in Fig. 2;

Fig. 4 is an enlarged fragmentary detail showing a typical locking provision for the removable storm sash and screen panels;

Fig. 5 is a view similar to that of Fig. 2, but illustrating a modification which is an all metal window assembly; and,

Fig. 6 is a further modification of the present invention showing an all wood window assembly in fragmentary detail only.

Referring in particular to Figs. 1, 2 and 3, a preferred construction is shown in connection with a window frame utilizing wood parts and having metal sash therefor. The window frame it includes the sill II, the lintel or head i2 and the jambs l3, all of which are arranged in a known manner to receive in sliding relation metal sash consisting of the upper or outer sash i4 and the lower or inner sash l5. Each metal sash is provided with the usual glass pane 16.

In Fig. 2, the lintel or head I2 includes a head member provided with an outer stop rail 2! and an inner bead 22. The head 20 also carries an intermediate rail 23 which cooperates with the stop 2| to form an outer slideway 24 for the outer sliding sash M. In like manner, rail 23 cooperates with the bead 22 to form an inner slideway for the inner sash 15. Each of the jambs 13 includes a jamb member ll (Fig. 3) provided with an outer stop member 26 (which cooperates with the head stop member 2|) and an inner bead 21 (which cooperates with the bead 22 carried by the head 20). In addition, each lamb member l7 carries a parting strip 28 which is adapted to cooperate with the parting rail 23 of the head 20 to separate the outer slideway 24 for the sash Hi from the inner slideway 25 for the sash l5. The jamb member ll of Fig. 3 is duplicated by one opposed thereto in the frame assembly. The sill H includes a sill member is which carries a rail adapted to cooperate with the parting strips 28 carried by the respective jamb members I! so that the sliding sash l4 and l having slideway throughout the vertical extent of the frame assembly. The sill member it carries at its inner margin a moulding strip 3!, as is understood.

The head rail 23, Fig. 2, is provided with an outer stop 33 formed by the rabbet 3a. In like manner, the sill rail is provided with stop formed by the rabbet 36 and each of. the jamb parting strips 28 (Fig. 3) is provided with the stop 3'! formed by a rabbet 38. The cross rail of this assembly is shown at ill, and this rail is located between the meeting rails 15A and MA of the sliding sash i5 and 14, respectively, when in their closed position. Cross rail G0 is provided with outer stops 4| and 42 and is provided inwardly thereof with locating means -13 and M at the upper and lower sides thereof. The cross rail may also be provided with suitable weather stripping elements, such as that shown at $5 and it, adapted to be engaged by the respective meeting rails MA and 15A when the sliding sash is disposed in closed position.

The respective rails 23, 3t and it, together with the parting strips 28 carried by the opposite jamb members l'l, form intermediate frame elements of the window assembly. These frame ele ments are formed from insulating materials and act to separate and insulate the outer and inner sliding sash members l4 and i5, so that there is no direct contact therebetween. In addition to this feature, these rails and strips constitute a irame assembly in which removable and. interchangeable storm sash and screen panels may be placed without necessitating the usual hazard of mounting the storm sash or screen panels from the outside of the building. The typical storm sash in Fig. 2 is provided with a channel frame so that one side of the frame may be mounted over the locating means as on the cross rail it. The remainder of the frame will then be located against the stop means 33 and 37 heretofore described. In a like manner, the lower storm sash 5i has its upper channel frame member located over the locating means it on cross rail 46. The remainder of its frame will then be seated against the stop means 37 and 35.

In Figs. 1, 3 and 4, suitable locking means has been shown for the purpose of retaining the storm sash 58 and 5i in position. This locking means comprises a plurality of detents 52, a typical one being shown in Figs. 3 and 4 pivoted in the parting strips 23 at 53. Each detent 52 can be moved to a position projecting from a suitable recess 54, as shown in connection with Figs. 3 and 4. When so projected, each detent 52 lies against the inner face of the storm sash frame, but when pivoted into the recess 54 is entirely removed from any obstructing relation with the storm sash frame. As shown in Fig. l, a pair of locking detents 52 have been shown for the upper storm sash 50 and a similar pair 52 have been shown in dotted outline for the lower storm sash 55. Screen panels are mounted in like manner, as shown in fragmentary part only in Fig. 6. In the construction of the screen panels such as that shown at 55 in Fig. 6 a frame substantially similar to and interchangeable with the storm sash 50 and El is employed and a suitable screen material 55 is mounted in the frame.

What has been described in connection with Figs. 1, 2 and 3 with respect to the vertical sliding sash type window assemblies shown, applies equally as well to the window assembly having side sliding sash. In a similar way, the provision for mounting removable storm sash 5G and El for interchangeable screen panels 55 is readily cared for by utilizing the cross rail and parting strip provisions herein described.

Fig. 5 illustrates a modification which includes an all-metal window frame and sash assembly. In general, the all-metal frame includes the sill 55, the head 6i and the jamb members $2 for each side extending between the sill and head. Only one jamb member 62 is shown however. This frame provides an inner slideway 63 for the inner metal sash 64 and an outer slideway 65 for the outer metal sash 6G. The slideways E53 and 65 are separated by means of a head rail er, a sill rail 88, a jamb rail 69 (one being carried by the opposite jamb member 52 not shown) and the cross rail 10 which is disposed to lie between the meeting rails MA and 66A of the inner and outer sliding sash, 64 and 86 respectively. These frame elements El, 68, 69 and iii are formed of an insulation material such as wood or plastic, for example, and are suitably recessed or rabbeted to receive the interchangeable storm sash 5G and 5! and screen panels 55 heretofore described in connection with Fig. 2 and Fig. 6. Here again, the cross rail i is provided with an upper locating means H for the storm sash 5B and a lower 10- eating means 72 for the storm sash 5i. While not shown in Fig. 5, it is understood that the locking detent 52 of Fig. 4 may be utilized for securing each of the storm sash units in place in this modified window. It is pointed out, in connection with the all-metal window frame and sliding sash, that the insulation material of the head, sill and cross rails and parting strips prevents any metal-to-metal contact of the sliding sash 6d and 66 with each other or with the metal storm sash 5t and 5|. The interruption of metalto-metal paths of heat transfer materially contributes to the reduction in formation of condensation or ice in or on a window assembly of this type.

In Fig. 6 there is illustrated a further modified window assembly showing the all wood construction thereof. This View is similar to that of Fig. 3 and similar parts in Fig. 6 have been indicated by similar numerals of reference increased by one hundred. Accordingly, this modified construction includes a cross rail am of the type shown at 4!! in Fig. 2, a parting strip I28 for each jamb member Ill and slide ways HM and I25 for wood sash. A fragmentary portion of a typical wood sash is shown at 75 in the outer slideway ifi l. Where the frame is made of wood, it is preferred to form the frame elements, such as the head, sill and cross rails and jamb parting strips, of wood also.
